Overview
The BC817-16W is a silicon NPN bipolar junction transistor manufactured by Infineon Technologies. It features a maximum collector current of 500 mA and a collector-emitter voltage rating of 45 V. The device offers a DC current gain (hFE) range of 160 to 400, with a transition frequency of 100 MHz. It operates within a temperature range of -55°C to +150°C and has a power dissipation capacity of 310 mW.
Feature Summary
- High DC current gain ranging from 160 to 400 for effective signal amplification
- Transition frequency of 100 MHz suitable for general-purpose switching applications
- Robust thermal performance with a maximum operating junction temperature of 150°C
Applications
- General-purpose switching circuits
- Linear amplifier stages
- Driver circuits for low-power loads
Procurement Notes
Verify the specific suffix 'W' against official Infineon documentation to confirm package type and tape/reel specifications. Ensure the hFE bin matches the required 160-400 range for the target application. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a standard NPN BJT with moderate current handling and high gain is required. The 45V rating suits low-voltage logic interfaces. Consider the SOT-23 or similar surface-mount package availability for PCB layout constraints. Verify thermal management requirements for continuous operation near the 310 mW limit.
Part Context
This component belongs to the BC817 series of general-purpose NPN transistors. It is widely used in consumer electronics and industrial control systems where reliable switching and amplification are needed. The series is known for its compatibility with standard surface-mount processes and broad availability across multiple manufacturers.
Replacement Considerations
Compatible substitutes include BC817-16 variants from Diodes Incorporated, Nexperia, and Diotec Semiconductor. Ensure equivalent electrical parameters such as VCEO, IC, and hFE ranges are met before substitution.
